Title:	The Complete Endodontic Obturation of an Avulsed Immature Permanent Incisor With Mineral Trioxide Aggregate: A Case Report
Abstract:	The use of mineral trioxide aggregate (MTA) for complete endodontic obturation of an immature maxillary central incisor is reported. The injured tooth of a 9-year-old male was avulsed secondary to a sports-related traumatic event. Early attempts at pulpal re­vascularization of the replanted tooth proved unsuccessful, as evidenced by radiographic signs of external inflammatory root resorption in the middle to cervical thirds of the root. Calcium hydroxide apexification over a 1-year period promoted cessation of the resorp­tive process, but was unable to adequately form an apical root canal barrier. Due to the extent of external resorption and the lack of an apical stop, a novel endodontic treatment using mineral trioxide aggregate was utilized. At 865 days post-injury, the tooth remained asymptomatic with clinical and radiographic evidence of periodontal health. (Pediatr. Dent. 2006;28:273-278)
